The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Hastings, NE wrote its last area forecast discussion before the first event at Aug 10, 5:44 AM CST, 2 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 644 AM CDT MON AUG 10 2009 .AVIATION...12Z TAF. PRIMARY CONCERN LIES IN THE FIRST FEW HOURS OF THIS TAF PERIOD...WITH THE LOW LEVEL STRATUS AND FOG IN THE AREA. MOSTLY CLEAR SKIES HAVE ALLOWED TEMPS TO COOL...AND WITH DEW POINTS LINGERING IN THE LOWER 60S AND LIGHT WINDS...THIS HAS ALLOWED FOR AT TIMES DENSE FOG TO DEVELOP AT THE TERMINAL...BRINGING PERIODIC LIFR CONDITIONS. EXPECT THIS TO BE THE CASE FOR A FEW MORE HOURS...ONCE THE SUN GETS UP AND BURNS THIS OFF CONDITIONS WILL IMPROVE. ANOTHER CONCERN IS WITH PRECIPITATION CHANCES THROUGH THE DAY AS AN UPPER LEVEL DISTURBANCE MOVES OUT OF THE ROCKIES AND THROUGH THE CENTRAL PLAINS. EXPECT BULK OF ACTIVITY TO REMAIN TO THE SOUTH OF THE TERMINAL...BUT MAY SEE A FEW SCT SHOWERS THIS MORNING. WINDS ARE TRICKY...AND WITH A WEAK SFC PATTERN OVER THE AREA...DETERMINING A PREVAILING DIRECTION IS DIFFICULT. EXPECTING VERY LIGHT WINDS THROUGH THE TAF PERIOD...WITH A GENERAL NORTHERLY DIRECTION. && .PREV DISCUSSION... /ISSUED 327 AM CDT MON AUG 10 2009/ DISCUSSION...THE PRIMARY ISSUE IN THE NEAR TERM WILL BE THE CHANCE OF THUNDERSTORMS TODAY. EARLY MORNING SURFACE ANALYSIS PLACED A FRONTAL BOUNDARY FROM NORTHWEST MISSOURI INTO SOUTHWEST KANSAS. EARLY MORNING WATER VAPOR IMAGERY SHOWED A WAVE MOVING ACROSS NORTHERN COLORADO...WHILE ANOTHER WAVE WAS MOVING INTO EASTERN COLORADO. THESE FEATURES HAVE MANAGED TO HELP IGNITE CONVECTION ACROSS PARTS OF NORTHEAST COLORADO EARLY THIS MORNING. THE 00Z NAM AND GFS BOTH GENERALLY AGREE THAT THE FRONTAL BOUNDARY SHOULD REMAIN SOUTH OF THE FORECAST AREA TODAY. IT APPEARS THE MAIN CHANCE OF THUNDERSTORMS ACROSS THE FORECAST AREA SHOULD COME FROM THE COLORADO WAVES. THE 00Z NAM AND GFS BOTH BRING THE WAVES ACROSS LATER TODAY INTO THIS EVENING. WILL CONTINUE TO CARRY A CHANCE OF THUNDERSTORMS ACROSS THE ENTIRE FORECAST AREA TODAY AS THE WAVES MOVES ACROSS. GENERALLY AGREE WITH THE SPC DAY 1 OUTLOOK IN THAT THE MORE ORGANIZED SEVERE THREAT WILL PROBABLY BE NEAR THE FRONTAL BOUNDARY...HOWEVER AM A BIT CONCERNED THAT THERE COULD BE AN ISOLATED SEVERE THREAT ACROSS JUST ABOUT THE ENTIRE FORECAST AREA BY LATE MORNING/EARLY AFTERNOON. 0-1KM MLCAPE VALUES ARE FORECAST TO BE IN THE 1000-1500 J/KG RANGE THIS AFTERNOON WITH 0-6KM SHEAR OF 35 TO 40 KTS. WILL GO AHEAD AND MENTION THE POSSIBILITY OF ISOLATED SEVERE THUNDERSTORMS IN THE HAZARDOUS WEATHER OUTLOOK IN CASE A FEW OF THE STORMS CAN TAP INTO THE GREATER INSTABILITY. WILL GRADUALLY END THE CHANCE OF THUNDERSTORMS FROM WEST TO EAST TONIGHT AS THE UPPER WAVE SHIFTS ACROSS THE REGION. TEMPERATURES THIS AFTERNOON WILL BE A BIT TRICKY SINCE THERE WILL LIKELY BE CLOUDS SPREADING INTO THE REGION AS THE WAVE APPROACHES. HAVE OPTED TO GO WITH THE COOLER SIDE OF GUIDANCE WHICH GIVES HIGHS MAINLY IN THE LOWER TO MID 80S. ANOTHER POTENTIAL ISSUE FOR THIS MORNING IS FOG. LOW DEWPOINT DEPRESSIONS ARE IN PLACE OVER MUCH OF THE FORECAST AREA...WITH SOME LOCATIONS ALREADY REPORTING REDUCED VISIBILITIES IN FOG. RUC FORECAST SOUNDINGS SHOW THIS TO SOME DEGREE WITH A VERY NARROW AREA OF LOW LEVEL SATURATION IN THE FORECAST SOUNDINGS ACROSS MAINLY THE EASTERN PORTION OF THE FORECAST AREA. WILL CARRY PATCHY FOG IN THE EAST EARLY THIS MORNING...BUT GET RID OF IT BY 14 OR 15Z. A DRY PERIOD IS EXPECTED FROM TUESDAY INTO THE MIDDLE OF THE WEEK AS THE UPPER RIDGE AMPLIFIES ACROSS THE REGION. THIS WILL ALSO BRING WARMING TEMPERATURES WILL HIGHS ON TUESDAY AND WEDNESDAY IN THE UPPER 80S TO AROUND 90...RISING TO THE LOWER TO MID 90S ON THURSDAY. AVIATION...06Z KGRI TAF. DRY WEATHER CAN BE EXPECTED AT KGRI THROUGH THE NIGHT. HOWEVER...SOME FORECAST MODELS SHOW AT LEAST SOME POSSIBILITY OF CONVECTION BY TOMORROW AFTERNOON. THIS CHANCE SEEMS FAIRLY LOW BUT NOW APPEARS HIGH ENOUGH TO WARRANT MENTIONING IN THE TAF WITHIN A PROB30 GROUP. WINDS WILL REMAIN VERY LIGHT THROUGH THE TAF VALID PERIOD. EXPECT VFR CONDITIONS FOR THE MOST PART BUT MAY BRIEFLY GET MVFR CONDITIONS AROUND SUNRISE. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. &&
